CHARLES B. HURST, OF CHILLICOTHE, OHIO.

001m ort GRAIN CRIB.

To all whom it may concern:

Be it known that I, CHARLES B. HURs'r, a citizen of the United States, residing at Chillicothe, in the county of Ross and State 5 of Ohio have invented certain new and useful Improvements in Corn or Grain Cribs, of which the following is a specification.

My invention relates to improvements in cribs for corn and grain.

The object of my invention is to rovide a device of this character which shall be simple and durable in construction and cheaply built, and also one which will be proof against the invasion of rats, etc.

A further object of my invention is to provide improved means for ventilating a struc ture of this kind.

My invention consists In the construction and combination of parts hereinafter de- 20 scribed and set forth in the claims.

a section of the central support.

broken. and shown in section to better illustrate the interior, this view showing some features not shown in Fig. tail of one of the ventilators shown in Fig. 5. Like" parts are represented by similar 1:3 characters of'reference.

, In said drawings (1 represents the floor or v base of the structure, formed with a series of radial grooves, a, open at the top and terminating at a common point in the center,

4o this floor being constructed preferably of cement.

a a represent sections of cement extending around the floor portion to form the side walls of the structure, those sections, of, ex-

tending up for any suitable distance and being joined together b a series of interengaging tie-rods, e, in t manner described in my prior patent No. 767,690 issued Aug. I6, 1904. Partly-embedded in these cement i side wall sections are a series of vertical supporting-posts b. The upper end of these posts are reduced as shown in b, Fig. 3, and fitting over these reduced portions, are a series of connecting beams, 1)", these connect- 5." ing beams forming supports for. one end of Specification of Letters Patent.

the rafters, b the inner ends of the rafters bein supported by the central post, 0, to Whic they may be nailed or secured in any suitable manner. The roofing (not shown) may be of an desired construction.

The centre post, 0, is constructed of four walls, c c c 0, so as to form a passage way throughout its entire length, the lower end of this hollow sup ort communicating with the grooves, a, any the upper end extending through the roof and being 0 en to the atmosphere. The side walls are urther spaced a art by spacing blocks, 0", as shown, so that t e hollow central support is ractioally open to the atmosphere throug out its entire len th.

he radial grooves, a communicate with the outside atmosphere through the medium of openings, (1 in the cement side wall sections; these openings being adapted to extend through the vertical supporting posts, I), there preferably being one of these posts for each radial groove and said posts being embedded in the cement side wall at point where the outer ends of said grooves terminate, which is preferably at the joints of the cement sections. placed in the openings, a to trance of mice and rats.

In Fig. 5 are shown a series of auxiliary Screens are preferably prevent the enhollow ventilators, c, which communicate with air passage of said central post, 0, radiate therefrom and join the radial grooves, a), in the floor of the structure; these auxiliary ventilators being constructed in the same manner as the central post, the side -walls, e, a, e and e being spacedv apart by blocks, a", shown in Fig. 6. These auxiliary ventilators will also act as supports for the central post, 0.

Secured to the vertical supporting posts, b, above the cement side walls, a, are a series of slats, 5, these slats being preferably wired to the supporting )osts as shown and being adapted to slighty over-hang the cement side walls as shown at If, to guard agair'ist rats jumping up from the ground and securing a footing on the side walls.

In Fig. 4 I have illustrated a door d, located in the cement side walls. d represents the door frame, to the sides of which are secured eyes, it, to which are secured the series of tic-rods (1., the tension ontlicse tierods serving to hold the frame securely in position. To prevent the frame from spreading when the tension is put on the tie-rods and before the cement work is put in, I provide a series of braces, W, on each side of the frame.

By the construction described it will be seen that I have rovided a structure which will be substantia l and of a permanent character; one that will be thoroughly ventilated; one that will be proof against the im;

I dial grooves in said floor, a central hollow post vasion of rats and other rodents; and one that can be built in sections and readily trans orted from the factory and easily and quic y placed together.

Having thus described my invention, I clain1:

1. In a grain crib, a floor, said floor having a series of air passages, an air flue open at its sides, and connections between said'fioor air plazsages and said flue, substantially as specie 2. In a grain crib, a central vertical hollow post, said hollow post having openings on its sides, and a floor havin a laterallyextending air passage therein w rich communicates with said hollow post at its inner end and with the atmosphere at its outer end, substantially as specified.

3. In a grain crib, a floor, side walls, and an air flue, open at its sides, said floor having air passages connecting with the bottom of said air flue and extending through saidside auxiliary air dues or ventilators extending flue having from said air passages to said main air flue,

substantially as s ecified.

5. In a grain cri afloor, a series of open raconnecting with said ooves 'at the bottom, said hollow post be1n open at intervals along its sides, and sai grooves being open to the atmosphere at their outer ends, substantially as specified.

6. In a grain crib, a central hollow post open at the sides, a floor having a series ofa floor having air pasradial air passages connecting with said hollow post, side Walls having air inlets connecting with said air assages, vertical supports supported by said side walls having a series of open slats above said side walls, and a roof supported by said vertical supports, substantially as specified. y

In testimony whereof, I have hereunto set my hand this 3d day of October 1907.
